The result of every match pretty well perfectly predicted by looking at the world rankings on the eve of the tournament.
Let's hope for some upsets soon.
Let me try to guess some upsets in the pool stages (defined as team beats a team higher in the rankings)
Wales might lose to Fiji (outside chance)
Wales might lose to Australia (strong chance)
Australia might lose to Fiji (outside chance)
Scotland might lose to Japan (low chance)
England might lose to Argentina (low chance)
England might lose to France (strongish chance)
There are probably other possibilities involving non top tier teams, but I think that's it in terms of teams expecting to get into the knock out stage.
